Or HaChaim on Exodus 33:15/אור החיים על שמות ל״ג:ט״ו

1 ואם אין פניך הולכים, "Unless Your face will go, etc." Moses was not satisfied with G'd's previous offer and said that unless G'd's face would go with them as of now the people would be lost, and there was no point in even beginning their ascent towards the Holy Land. His reasoning was that the only way he could be certain that he had indeed found favour in G'd's eyes was the method employed by G'd in accompanying the Jewish people. He referred to Israel's distinction of G'd relating to them as the Attribute represented by His Ineffable Name. Moses was dissatisfied that only he and not the entire people should be the beneficiaries of the "great light" which G'd had promised to bestow on Moses in verse 14. [The author appears to feel that the fact that G'd did not tell Moses in verse 14 that His Attribute would walk with the people instead of ahead of the people, made Moses refuse the offer. Ed.] He prayed for G'd to accompany the people as His attribute of the Ineffable Name, i.e. as the attribute of Mercy. G'd agreed to this request also when He said: "I will also carry out this matter which you have spoken of for you have found favour in My eyes." G'd was careful to let Moses know that His consent was due to His fondness of Moses, not because of His being fond of the people.
